As analyses of system behavior and complexity through computer modeling and simulation have been growing, high performance modeling is noticed to handle behavior and complexity of modern large-scale systems. The high performance modeling focuses on high resolution representation of system and performance improvement. This paper presents a quantized system modeling as an effective high performan...

Discrete event simulations (DES) provide a powerful means for modeling complex systems and analyzing their behavior. DES capture all possible interactions between the entities they manage, which makes them highly expressive but also compute-intensive. These computational requirements often impose limitations on the breadth and/or depth of research that can be conducted with a discrete event sim...

In many Discrete-Event Systems (DES) both state and event information are of importance to the systems designer. As a first step towards obtaining hierarchical models of systems, the behavior of Discrete-Event Systems with unobservable transitions and state output maps is considered. Observers for deterministic DES are generalized to nondeterministic DES and characterized using the join semilat...

Representing human behavior and cognition, from individuals to societies, presents a range of challenges to the modeling and simulation community. A common thread through many of these challenges is formulating an authentic representation of time. Many of the issues related to time representation, from the sequencing of cognitive decision processes and information processing, to communication a...

Simulation is the best tool used to predict the behavior of real world systems. For the analysis of complex systems, simulation is often used prior to the operation of the system as a mediator for a dynamic situation. This chapter presents the issue of complex systems simulation through Discrete Event Simulation (DES) and System Dynamics (SD) techniques. The Authors original approach stands in ...

In this paper, we investigate output accuracy for a Discrete Event Simulation (DES) model and Agent Based Simulation (ABS) model. The purpose of this investigation is to find out which of these simulation techniques is the best one for modelling human reactive behaviour in the retail sector. In order to study the output accuracy in both models , we have carried out a validation experiment in wh...

The present paper approaches the development and application of a Discrete Event Simulation (DES) model with a Multiple Criteria Decision Analysis (MCDA) tool for the simulation and sizing of a closed-loop maritime transportation system. This system is responsible for the supply of raw materials, especially iron ore, to a steel plant, and its sizing involves the analysis of the transportation f...
